Description
Technical field
The present invention relates generally to tubing field, relates in particular to a kind of polypropylene corrugated tube and preparation method thereof.
Background technology
Polyacrylic degree of crystallinity is high, compound with regular structure, thereby there is good mechanical property.The absolute value of Mechanical Properties of PP is higher than polyethylene, but in plastic material, still belongs to kind on the low side, and its tensile strength only can reach 30 MPa or slightly high level.The polypropylene that isotactic index is larger has higher tensile strength, but with the raising of isotactic index, the shock strength of material declines to some extent, but no longer changes after dropping to a certain numerical value.
Temperature and loading rate are very large to polyacrylic Toughness.When temperature is during higher than second-order transition temperature, impact fracture is ductile rupture, lower than second-order transition temperature, is brittle rupture, and impact value significantly declines.Improve loading rate, can make the temperature that ductile rupture changes to brittle rupture increase.Polypropylene has excellent counter-bending fatigability, its goods bent 106 times and do not damage at normal temperatures;
Polyacrylic chemical stability is fine, outside decapacitation is corroded by the vitriol oil, concentrated nitric acid, all more stable to other various chemical reagent, but low-molecular-weight aliphatic hydrocarbon, aromatic hydrocarbon and chlorinated hydrocarbon etc. can make polypropylene soften and swelling, its chemical stability also increases with the increase of degree of crystallinity simultaneously, so polypropylene is applicable to making various chemical pipelines and accessory, anticorrosion ability is good; Preparing aspect corrugated tube, polypropylene has higher Young's modulus and the lower features such as density, can meet the performance requriements of corrugated tube completely.
